Ajuste sacral en lifting glúteo tras grandes perdidas ponderales / Sacral contouring in gluteal lifts after massive weight loss

Introducción y objetivo: Las alteraciones en la región glútea después de una pérdida significativa de peso o una cirugía bariátrica aparecen como piel fácida, reducción de tejido adiposo y pérdida de masa muscular, provocando diversas quejas entre los pacientes. A diferencia de los autores que predefinen la cantidad de tejido a resecar en la región sacra, empleamos este refinamiento al final de la operación, permitiendo la retirada de más piel, corrigiendo asimetrías y dando forma al surco glúteo, según la anatomia de cada individuo.Material y método.Sometimos a lifting glúteo a 15 pacientes. En 12 usamos un colgajo adiposo para proyectar la mitad superior de la región glútea. En 3, además del colgajo adiposo incluimos una prótesis de silicona a través de la misma incisión.Resultados.Entre los 15 pacientes atendidos recogimos las siguientes complicaciones: 1 caso de hematoma tratado solo con aspiración mediante punción; 2 casos de seroma con drenaje espontáneo a través de la herida quirúrgica; y 2 casos de dehiscencia parcial de suturas, con revisión de la cicatriz solo en 1 de estos casos.Conclusiones.En nuestra experiência, el ajuste cutáneo de la región sacra realizado al final de un lifting de glúteos, proporciona una mejor simetría y un posicionamiento más preciso del nuevo surco glúteo.

Background and objective: Alterations in the gluteal region after significant weight loss or bariatric surgery appear as sagging skin, reduced adipose tissue and loss of muscle mass, causing a variety of complaints from patients. Unlike the authors who pre-define the amount of tissue to be resected in the sacral region, we performed this refinement at the end of the operation, allowing the removal of more skin, correcting asymmetric aspects and shaping the gluteal sulcus, depending on the individual anatomy.Methods.Fifteen patients underwent gluteal lifting. In 12 we used an adipose flap to project the upper half of the gluteal region. In 3 of them, in addition to the adipose flap, we included a silicone prosthesis through the same incision.Results.Among our 15 patients we noticed the following occurrences: 1 case of hematoma treated only with aspiration puncture; 2 cases of seroma with spontaneous drainage through the surgical wound; and 2 cases of partial dehiscence of the sutures, with scar revision required in only 1 of these cases.Conclusions.In our experience, the skin adjustment of the sacral region performed at the end of a gluteal lifting, provides better symmetry and more precise positioning of the new gluteal groove.

Nanocellulose obtained from residues of peach palm extraction (Bactris gasipaes).

The large amount of residues generated by the peach palm agroindustry and its cellulose content (34 g 100g-1) motivated the present investigation, where outer sheaths were used for nanocellulose production through ultrafine grinding. Protocols combining different chemical delignification with defibrillation intensity (10 and 20 cycles) were applied and their influence over some properties and characteristics of nanofibers evaluated. At all protocols applied it was possible produce cellulose at nanometric level (widths ˜100 nm), with high crystallinity index (49.8-54.5%) and great thermal stability. The delignification influenced the defibrillation, where lignin removal resulted in well dispersed bundles of fibrils with lower widths. Lower lignin contents combined with higher shear forces released more nanofibrils, with more adsorbed water with defibrillation extension. These behavior influenced the suspension stability, that was higher at larger number of cycles (20). The results evidenced that was possible produced FNC with appropriate technical characteristics from pupunha discards.

Oral peripheral nerve sheath tumors: A clinicopathological and immunohistochemical study of 32 cases in a Brazilian population.

BACKGROUND: Oral peripheral nerve sheath tumors (OPNSTs) are reactive or neoplastic diseases that develop from proliferation of the nerve itself or their limiting sheaths. Here we describe the clinicopathologic data of OPNSTs observed in a sample of the Brazilian population and evaluate the expression of molecules associated with neural biology to determine their usefulness in the diagnosis. MATERIAL AND METHODS: Descriptive study of cases diagnosed as OPNSTs, from the Pathology Laboratory at the School of Dentistry/ Federal University of Uberlandia, followed by an immunohistochemical study of S-100, CD57, neurofilament protein (NFP) and epithelial membrane antigen (EMA). RESULTS: OPNSTs comprised 0.27% of all biopsies. There were eight patients with neurofibromas, eight with traumatic neuromas, seven with schwannomas, five with granular cell tumor (GCT), and four with palisaded encapsulated neuromas (PEN). Women were more frequently affected (60.6% of the cases). Tongue and lips prevailed as the most frequent sites. S-100 was reactive in 100% of the cases. Neural fibers evidenced by CD57 reactivity of their Schwann cells were always nested in bundles within neurofibromas and GCT, absent within schwannomas and dispersed within PEN. Reactivity for NFP was limited to axons and then followed the same pattern of CD57, though much less evident. Reactivity for EMA was observed in the capsular tissues and perineurium of nerve fascicles, and absent in parenchymal cells of GCT. CONCLUSIONS: This study showed that OPNSTs are rare, widely benign and often found in tongue and lips. OPNSTs evolve from a common origin to distinct histological patterns, with eventual overlapping in their clinical and morphologic features. The arrangement of reactive residual neural fibers for CD57 can be a useful staining in the differential diagnosis of OPNSTs. Key words:Peripheral nerve sheath tumors. Oral cavity.

Uso exclusivo de fios absorvíveis em fendas labiopalatais / Exclusive use of absorbable suture threads in cleft lip and palate

INTRODUÇÃO: O tratamento de fendas labiopalatais tem etapas que podem trazer traumas psicológicos consideráveis aos pacientes e familiares. O uso de fios absorvíveis pode eliminar um destes momentos desconfortáveis. Contudo, a utilização exclusiva deste tipo de material de síntese ainda não é a preferência de todos os cirurgiões, principalmente em planos musculares. MÉTODOS: Levantados os dados dos pacientes operados no Hospital Universitário da Universidade Federal do Rio de Janeiro, submetidos à correção de fendas labiais ou palatais, nas quais foram utilizados somente fios absorvíveis (poliglecaprona 25 - Monocryl® ou poliglactina 910 - Vicryl Rapide®) em todos os panos de sutura (mucosa, músculo, pele). O período avaliado foi de 2007 a 2014. RESULTADOS: Encontramos 360 pacientes que se enquadraram no estudo. Não observamos diferenças quanto ao aspecto local das feridas durante o processo de absorção dos fios. A incidência de deiscências ou fístulas se manteve abaixo de 1% e não houve complicações relacionadas ao objetivo do estudo. As cicatrizes não se mostraram, a longo prazo, diferentes das obtidas com o uso de fios inabsorvíveis, utilizados em outros tipos de cirurgias. CONCLUSÕES: O uso exclusivo destes fios absorvíveis se mostrou uma opção eficaz e segura. Proporcionou cicatrizes de boa qualidade, força tênsil adequada (mesmo em planos musculares) e não observamos complicações relacionadas ao processo de absorção dos materiais empregados.

INTRODUCTION: The treatment of orofacial clefts comprises steps that may result in considerable psychological trauma for patients and their caregivers. The use of absorbable sutures may help to eliminate these uncomfortable situations. However, the exclusive use of this synthetic material is still not preferred by surgeons, particularly in the muscle planes. METHODS: Data from patients who underwent surgery at the University Hospital of the Federal University of Rio de Janeiro from 2007 to 2014 were used. The patients underwent correction of cleft lip or palate, using only absorbable sutures (poliglecaprone 25 - Monocryl® or polyglactin 910 - Vicryl Rapide®) in all suture planes (mucosa, muscle, skin). RESULTS: We found 360 patients who met the inclusion criteria for this study. We did not observe differences in terms of the local appearance of the wounds during the suture absorption process. The incidence of dehiscence or fistula cases was below 1%, and there were no complications regarding the objectives of the study. In the long term, the scars did not differ from those obtained with non-absorbable sutures used in other types of surgeries. CONCLUSIONS: The exclusive use of absorbable sutures was shown to be an efficient and safe option. These resulted in good quality scars and adequate tensile strength (even in muscle planes), and we did not observe complications related to the absorption process of the material used.

Plastic surgery in chest wall reconstruction: relevant aspects - case series / A cirurgia plástica na reconstrução da parede torácica: aspectos relevantes - série de casos

Objective: to discuss the participation of Plastic Surgery in the reconstruction of the chest wall, highlighting relevant aspects of interdisciplinaryness. Methods: we analyzed charts from 20 patients who underwent extensive resection of the thoracic integument, between 2000 and 2014, recording the indication of resection, the extent and depth of the raw areas, types of reconstructions performed and complications. Results: among the 20 patients, averaging 55 years old, five were males and 15 females. They resections were: one squamous cell carcinoma, two basal cell carcinomas, five chondrosarcomas and 12 breast tumors. The extent of the bloody areas ranged from 4x9 cm to 25x40 cm. In 12 patients the resection included the muscular plane. In the remaining eight, the tumor removal achieved a total wall thickness. For reconstruction we used: one muscular flap associated with skin grafting, nine flaps and ten regional fasciocutaneous flaps. Two patients undergoing reconstruction with fasciocutaneous flaps had partially suffering of the flap, solved with employment of a myocutaneous flap. The other patients displayed no complications with the techniques used, requiring only one surgery. Conclusion: the proper assessment of local tissues and flaps available for reconstruction, in addition to the successful integration of Plastic Surgery with the specialties involved in the treatment, enable extensive resections of the chest wall and reconstructions that provide patient recovery.

Objetivo: discorrer sobre a participação da Cirurgia Plástica na reconstrução da parede torácica, ressaltando os aspectos relevantes das associações interdisciplinares. Métodos: foram analisados prontuários de 20 pacientes submetidos a extensas ressecções do tegumento torácico, no período entre 2000 e 2014, quanto à indicação das ressecções, à extensão e à profundidade das áreas cruentas, aos tipos de reconstruções realizadas e às complicações. Resultados: entre os 20 pacientes, com média de 55 anos de idade, cinco eram do sexo masculino e 15 do feminino. Foram ressecados: um carcinoma espinocelular, dois carcinomas basocelulares, cinco condrossarcomas e 12 tumores de mama. A extensão das áreas cruentas variou de 4x9 cm até 25x40 cm. Em 12 pacientes as ressecções abrangeram o plano muscular. Nos oito restantes, a retirada do tumor atingiu a espessura total da parede. Para reconstrução foram utilizados: um retalho muscular associado à enxertia de pele, nove retalhos miocutâneos e dez retalhos fasciocutâneos da região. Em dois pacientes submetidos à reconstrução com retalhos fasciocutâneos houve sofrimento parcial do retalho, resolvido com o emprego de retalho miocutâneo. Nos outros pacientes não houve intercorrências com as técnicas empregadas, sendo necessária somente uma cirurgia. Conclusão: a adequada avaliação dos tecidos locais e dos retalhos disponíveis para a reconstrução, além da boa integração da Cirurgia Plástica com as especialidades envolvidas no tratamento, possibilitam extensas ressecções da parede torácica e reconstruções que propiciam a recuperação do paciente.

Utilização do retalho miocutâneo de grande dorsal, com extensão adiposa, nas reconstruções mamárias: uma opção para preenchimento do polo superior / Use of the myocutaneous latissimus dorsi flap with fat extension in breast reconstruction: an option for filling the upper pole

INTRODUÇÃO: As sequelas de mastectomia se apresentam de formas variadas exigindo, do cirurgião, experiência e criatividade para obter o melhor resultado na reconstrução de uma nova mama. Dentre as dificuldades para que este objetivo seja alcançado, está o desafio de um melhor preenchimento do polo superior da mama. O objetivo deste trabalho é apresentar uma opção terapêutica alternativa para correção do polo superior dentre as técnicas já existentes com este propósito. MÉTODO: A técnica cirúrgica utilizou o retalho de músculo grande dorsal com extensão gordurosa para preenchimento do polo superior da neomama durante sua reconstrução. A técnica descrita foi utilizada em 8 pacientes durante a reconstrução mamária tardia, com idades variando entre 39 e 70 anos. O tamanho desta extensão gordurosa variou entre 4,0 × 10,0 e 7,0 × 13,0 cm. O componente gorduroso do retalho foi avaliado após 3 meses através de ressonância magnética. RESULTADOS: Foram usados implantes mamários que variavam entre 270 e 435 ml. O acompanhamento pós operatório variou entre 3 meses a 1 ano. Ocorreram 2 casos de epidermólise (28%) na junção do retalho cutâneo com a área receptora. Não houve perda ou sofrimento do retalho. Os resultados demonstram clinicamente ou visualmente que a correção da depressão do polo superior da neomama foi alcançada adequadamente, bem como a viabilidade do retalho gorduroso, observada nos exames de imagem (ressonância magnética). CONCLUSÃO: A técnica proposta é uma alternativa adequada para o tratamento da maioria dos casos de reconstrução mamária em que se busca o preenchimento da depressão existente no polo superior da mama.

INTRODUCTION: The sequelae of mastectomy presents in numerous ways, requiring the experience and creativity of the surgeon to achieve the best result in the reconstruction of a new breast. One of the difficulties in achieving this objective is the challenge of adequately filling the upper pole of the breast. The objective of this work was to present an alternative therapeutic option for correction of the upper pole of the neobreast. METHODS: In our surgical technique, a latissimus dorsi muscle flap with fat extension is used for filling the upper pole of the neobreast during its reconstruction. The described technique was used in 8 patients during late breast reconstruction. The patients' ages ranged from 39 and 70 years. The size of the fat extension ranged from 4.0 × 10.0 cm to 7.0 × 13.0 cm. The fat component of the flap was evaluated after 3 months by using magnetic resonance imaging (MRI). RESULTS: Breast implants that varied in volume between 270 and 435 mL were used. The follow-up period after surgery ranged from 3 months to 1 year. Two patients had epidermolysis (28%) at the junction of the cutaneous flap and the receiver area. No graft loss or other complications occurred. Our results demonstrate clinically or visually that correction of the depression in the upper pole of the neobreast was satisfactorily achieved. The viability of the fat flap, as observed on MRI, was adequate. CONCLUSION: The proposed technique is a suitable alternative method for filling the depression in the upper pole of the neobreast in most cases of breast reconstruction.

Implante mamário redondo versus anatômico: algoritmo para escolha da forma adequada / Round versus anatomical breast implants: algorithm for choosing the appropriate form

INTRODUÇÃO: Vários cirurgiões têm suas próprias fórmulas ou protocolos para selecionar os volumes e formato de implantes mamários. Para determinar a escolha do formato, medimos as distâncias entre a borda superior da mama e a papila (A) e entre a papila e sulco submamário (B). Baseados nestas medidas, propomos um algoritmo para selecionar próteses redondas ou anatômicas. MÉTODOS: As avaliações pré-operatórias foram realizadas com a paciente em posição ortostática considerando-se as medidas: 1) da fúrcula esternal à papila, para avaliar a necessidade de retirada de pele supra-areolar; 2) da base da mama, para avaliar o volume do implante; 3) das distâncias A e B, para avaliar a forma do implante. Este algoritmo foi aplicado a 59 pacientes submetidas à mamoplastia de aumento. RESULTADOS: Utilizamos implantes redondos em 27 pacientes; nove tinham distância a = b, e 18 B > A. Empregamos implantes anatômicos em 32 pacientes. Os volumes dos implantes redondos variaram entre 195 cc e 425 cc, enquanto os implantes anatômicos ficaram entre 185 cc e 315 cc. Com relação às medidas pós-operatórias das pacientes que utilizaram implantes redondos, 26 (96,3%) mantiveram a proporção desejada com B > A ou A = B. Entre as pacientes com implantes anatômicos, as medidas de 25 delas (78,1%) mostraram alteração das proporções, de A > B para A = B ou B > A. CONCLUSÕES: Quando a distância A é igual ou menor que a distância B, recomendamos implantes redondos. Quando B < A, recomendamos implantes anatômicos.

INTRODUCTION: Several surgeons have their own formulas or protocols to select the volume and shape of breast implants. To determine the shape, we measured the distances between the upper edge of the breast and the papilla (A), and between the papilla and the inframammary fold (B). Based on these measurements, we propose an algorithm to select round or anatomical implants. METHODS: Preoperative assessment was performed with the patients in the orthostatic position. The following distances were considered: 1) from the sternal notch to the papilla, to assess the need for supra-areolar skin excision; 2) breast base, to assess the volume of the implant; 3) distances A and B, to evaluate the shape of the implant. This algorithm was applied to 59 patients undergoing augmentation mammoplasty. RESULTS: We used round implants in 27 patients; nine had a distance A = B, and 18 had B > A. We utilized anatomical implants in 32 patients. The volume of round implants ranged from 195 to 425 cc, whereas that of anatomical implants ranged from 185 and 315 cc. Regarding postoperative measurements of the patients who used round implants, 26 (96.3%) maintained the desired ratio with B > A or A = B. Among the patients with anatomical implants, 25 (78.1 %) showed proportional changes from A > B to A = B or B > A. CONCLUSIONS: When the distance A is equal to or smaller than the distance B, we recommend round implants. When B < A, we recommend anatomical implants.

Tratamento das áreas cruentas de perna com retalhos locais / Treatment of open wounds of the leg by using local flaps

INTRODUÇÃO: Até os anos 70, a reparação de perdas de substância na perna representava, quase sempre, um problema de solução muito difícil ou, até, insolúvel. Atualmente, embora ainda constitua um campo para os mais experientes, as áreas cruentas na perna já contam com várias técnicas confiáveis e algumas relativamente simples para sua reparação. Este trabalho visa equacionar condutas reparadoras de feridas de perna, utilizando tecidos locais. MÉTODO: Estudo retrospectivo pela análise de casos de reconstrução de perna com retalhos locais realizados pelos autores. Foram incluídos os retalhos dermoadiposos, fasciocutâneos, fasciossubcutâneos e musculares. RESULTADOS: Foram operados 70 pacientes que possuíam áreas cruentas na perna, em consequência de fratura de tíbia, osteomielite, perda tecidual isquêmica, úlcera crônica e tumoração de pele. Os resultados foram avaliados segundo etiologia, tipo de procedimento cirúrgico e complicações. CONCLUSÕES: A opção do tratamento de áreas cruentas de membros inferiores com retalhos locais é bastante válida. A escolha do retalho vai depender de condições locais da perna e da região anatômica afetada. No terço superior da perna, utilizamos retalhos fasciocutâneos baseados na rede vascular do joelho ou retalho de gastrocnêmio. Já no médio, os principais retalhos foram o solear e o fasciossubcutâneo de panturrilha. E, por fim, no inferior, o principal retalho usado foi o fasciossubcutâneo de panturrilha.

INTRODUCTION: Until the 70s, repairing loss of tissue in the leg was almost always difficult, or even impossible. Currently, only the most experienced surgeons are able to repair open wounds of the leg. Nevertheless, several reliable and simple techniques are currently available. This work aimed to evaluate repair techniques for leg wounds by using local tissues. METHOD: The authors performed a retrospective study of cases of leg reconstruction using local flaps. Dermoadipose, fasciocutaneous, fasciosubcutaneous, and muscle flaps were used. RESULTS: Seventy patients who had open areas in the leg due to tibial fractures, osteomyelitis, ischemic tissue loss, chronic ulcer, or skin tumor underwent surgery. Results were evaluated according to etiology, type of surgical procedure, and complications. CONCLUSIONS: The option of treating open wounds of the lower limbs by using local flaps is very valid. Selection of the flap type depended on local conditions in the leg, and the anatomical region affected. In the upper third of the leg, we used fasciocutaneous flaps, based on the vascular network of the knee, or gastrocnemius flaps. In the middle third of the leg, we used the soleus muscle as the primary flap, and fasciosubcutaneous flaps in the calf region. In the lower third of the leg, a fasciosubcutaneous flap of the calf was primarily used.

Seroma tardio após implantes mamários de silicone: três formas diferentes de apresentação, evolução e conduta / Late seroma after silicone breast implants: three different forms of presentation, evolution, and approach

INTRODUÇÃO: Os seromas tardios após mamoplastia de aumento são ocorrências pouco comuns, que podem se manifestar sem causa definida e cujo tratamento implica a retirada ou a troca das próteses. Este trabalho objetiva analisar 3 casos dessa complicação, ocorrida entre 1 ano e 10 anos de pós-operatório, tratados de formas distintas. MÉTODO: Foram analisados os dados de 3 pacientes que apresentaram seroma no pós-operatório tardio de inclusão de próteses de mama. Neste artigo são apresentados dados relativos a indicação da inclusão, tempo de evolução sem complicações, tipo de prótese e resultado da análise do material retirado ou drenado. RESULTADOS: Em 2 pacientes, foi realizada retirada bilateral das próteses, apesar de somente um dos lados ter sido afetado; na terceira paciente, procedeu-se à troca da prótese por outra de mesmo volume e tipo. Um dos casos foi diagnosticado como pus estéril. CONCLUSÕES: Previamente à inclusão de próteses mamárias, a paciente deve ser alertada para o fato de que sua decisão poderá ter implicações futuras, sendo, eventualmente, necessário trocá-las ou retirá-las, o que resultará em novas cirurgias e/ou novas cicatrizes.

BACKGROUND: Late seromas after augmentation mammaplasty are uncommon, can manifest without a defined cause, and can be treated by implant removal or replacement. This study aimed to analyze three cases of this complication that occurred 1-10 years postoperatively and were treated differently. METHODS: Data of three patients who developed late seroma after breast implant placement were analyzed. In this report, we present data on the indication for implant placement, time without complications, implant type, and the analytical results of the removed or drained material. RESULTS: Two patients underwent bilateral implant removal, although only one side was affected, and the implant was replaced with another of the same type and volume in the third patient. One case of sterile pus was diagnosed. CONCLUSIONS:Before undergoing breast implant surgery, patients should be informed of the implications of their decisions, such as the possible need to remove or replace them, resulting in more surgical procedures and/or new scars.

Use of autologous fibrin glue (platelet-poor plasma) in abdominal dermolipectomies.

BACKGROUND: Autologous plasma is endowed with properties that speed up healing, hemostasis, and adhesiveness, in addition to growth factors. Through an established protocol, it was possible to isolate thrombin, as well as the platelet-rich plasma (PRP) and platelet-poor plasma (PPP) fractions. The purpose of this study was to analyze autologous use of thrombin and PPP to foster adhesion between an abdominal dermoadipose flap and the aponeurotic surface in abdominal dermolipectomies. METHODS: The data from 40 patients who underwent abdominal dermolipectomies were analyzed, with 20 patients using thrombin and autologous PPP (Plasma group) and 20 patients with no intervention (Control group). An attempt was made to assess adhesive power by quantifying the serohematic liquid volume gauged during the postoperative days (POD), and also noting the incidence of seroma. Other variables such as age and body mass index (BMI) were also analyzed. RESULTS: The reduction in the aspiration drain debit was statistically relevant only on the first POD in the Plasma group. There was no reduction in the incidence of seroma in these patients. Similarly, age and BMI did not influence these outcomes. CONCLUSION: The PPP fostered adhesion between the abdominal dermoadipose flap and the aponeurotic surface only on the first POD and had no influence whatsoever on the incidence of seroma. There are few reports on the use of PPP for plastic surgery, particularly the autologous type, opening up possibilities for further research projects to expand its use.

Protocol for obtaining platelet-rich plasma (PRP), platelet-poor plasma (PPP), and thrombin for autologous use.

BACKGROUND: Plasma has been widely studied and used in many different situations to speed up healing with better tissue adherence and hemostasis. Research projects are now attempting to isolate platelet-rich plasma (PRP) and platelet-poor plasma (PPP), making better use of their properties, particularly during operations and for wounds that are slow to heal. In view of the wide diversity of industrial machines and extraction protocols, together with the variety of industrially produced biologic glues, this article suggests an option for obtaining PRP, PPP, and human thrombin for autologous use. METHODS: A way of obtaining PRP, PPP, and thrombin is reproduced through a protocol defined and established by the authors. Autologous thrombin and plasma were obtained through the collection and successive centrifugation of ten whole blood samples, until the desired hemocomponents were isolated, followed by quantitative and qualitative analyses of the elements obtained. RESULTS: The mean platelet concentration obtained was 6.03 × 10(8) platelets/ml, with a mean thrombin concentration of 33.54 nM, both values compatible with reports in the literature when different protocols are applied. CONCLUSIONS: The protocol described is a good option for the preparation and application of PRP, PPP, and autologous thrombin, particularly as they can be obtained simultaneously, eliminating the possibilities of viral contamination and allergic reactions. Moreover, the cost of this procedure is low, it is easy to perform, and replicable. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Avaliação histológica e de espessura das cápsulas orgânicas formadas ao redor de expansores de tecidos de superfície lisa ou texturizada em humanos / Histological and wall thickness assessment of organic capsules formed around smooth and textured tissue expanders in humans", "_e": "n

INTRODUÇÃO: A busca por um produto que realize expansão tecidual com dano mínimo aos tecidos envolvidos, retalhos mais distensíveis e de menor espessura, e menos sintomas clínicos durante o processo de expansão tem levado as empresas a fabricar expansores com diferentes superfícies (lisa ou texturizada). A literatura é bastante controversa em relação às vantagens da utilização de um ou outro tipo. Esses aspectos motivaram os autores a pesquisar eventuais diferenças capsulares que pudessem justificar a escolha clínica. MÉTODO: Foi realizado um estudo cego, prospectivo, sem critérios de exclusão, em 38 pacientes submetidos a expansão tecidual no Serviço de Cirurgia Plástica do Hospital Universitário da Universidade Federal do Rio de Janeiro (Rio de Janeiro, RJ, Brasil). Ao final do processo de expansão, foram coletados fragmentos da periferia, da base e da cúpula das cápsulas de 28 expansores de superfície lisa e de 14 de superfície texturizada, para estudo da espessura e de possíveis diferenças histológicas. RESULTADOS: Não houve diferenças entre os dois tipos de expansor quanto aos aspectos clínicos, ao tempo efetivo de expansão e aos planos de inclusão. Na avaliação dos parâmetros histológicos, não foram observados valores significativamente diferentes segundo a superfície do expansor. Não houve correlação entre espessura e tempo de permanência, e a diferença entre as espessuras máxima e mínima foi considerada igual para os dois tipos de superfície. CONCLUSÕES: Não há diferenças significativas do ponto de vista histológico, nem razões clínicas, que indiquem vantagens de um ou outro tipo de expansor no processo de expansão tecidual.

BACKGROUND: The search for an expander that can achieve tissue expansion, with minimum tissue damage, more distensible and thinner flaps, and fewer clinical side effects during the expansion process, has led to the testing of expanders with different surfaces textures (e.g., smooth vs. textured). The individual advantages of smooth and rough expanders are currently not known. This question has motivated research on capsules to determine which type of expander is best. METHODS: We conducted a double-blind, prospective study with no exclusion criteria on 38 patients already undergoing tissue expansion at Plastic Surgery Department at the Universidade Federal do Rio de Janeiro (University Hospital of the Federal University of Rio de Janeiro). At the end of the expansion process, samples were collected from the edge, base, and dome of capsules formed around 28 smooth and 14 textured expanders. Differences in capsule wall thickness and histology were examined. RESULTS: There was no difference in the clinical appearance, expansion time, or insertion planes between the two types of expanders. Additionally, no significant differences in histological characteristics were observed between the types of expander surfaces. In statistical analyses, no correlation between capsule wall thickness and expansion time or between the maximum and minimum wall thickness were observed. CONCLUSIONS: Therefore, we conclude that the two types of tissue expander surfaces are equivalent.

Implantes complementares na reconstrução mamária / Supplementary implants in breast reconstruction", "_e": "n

INTRODUÇÃO: A depressão na parede anterior da axila pós-mastectomia gera insatisfação das pacientes ao vestirem roupas mais decotadas; além disso, pode haver dificuldade na elevação do braço quando há aderências e retrações nessa região. Nessas pacientes, utilizamos implantes complementares, que reconstituem a anatomia local de forma satisfatória, oferecendo benefícios funcionais ao remover bridas cicatriciais. Esses implantes estão disponíveis em variados tamanhos e volumes, podendo ser empregada mais de uma prótese no mesmo local, se necessário. O objetivo deste estudo é demonstrar a experiência da Disciplina de Cirurgia Plástica da Universidade Federal do Rio de Janeiro (Rio de Janeiro, RJ, Brasil) com o emprego de implantes complementares na reconstrução mamária pós-mastectomia, buscando melhorar os aspectos estético e funcional da região axilar. MÉTODO: A inclusão de implantes de silicone complementares para reconstrução mamária pós-mastectomia foi realizada em 6 pacientes do sexo feminino, com idade entre 34 anos e 75 anos. O volume dos implantes variou de 20 ml a 120 ml. Largura, comprimento e profundidade da área da axila a ser preenchida foram mensurados, para definir volume, dimensões e número de implantes que seriam utilizados. A via de acesso utilizada para inserção dos implantes foi a cicatriz da reconstrução mamária. RESULTADOS: O seguimento pós-operatório variou de 6 meses a 8 anos, não sendo observada contratura capsular em nenhum caso. Todas as pacientes referiram melhora funcional na movimentação do braço, bem como satisfação com o resultado estético pela possibilidade de uso de roupas mais decotadas. CONCLUSÕES: A inclusão de implantes de silicone de formato semilunar no refinamento da reconstrução mamária é um método simples e de fácil realização, com resultados bastante previsíveis, necessitando apenas de uma cirurgia. Os implantes podem ser substituídos, aumentados ou removidos, se necessário.

BACKGROUND: Depression in the anterior wall of the axilla following mastectomy is distressing to patients when they wear summer clothing and may also cause difficulty in raising the arm if there are adhesions and retractions in the region. In these patients, we use supplementary implants that reconstitute the local anatomy in a satisfactory manner and which offer functional benefits by removing cicatricial adhesions. These implants are available in several sizes and volumes, and it is possible to use more than one prosthesis in the same location, if needed. The aim of this study is to report the experience of the Plastic Surgery Unit of the Federal University of Rio de Janeiro (Rio de Janeiro, RJ, Brazil) with the use of supplementary implants in breast reconstruction after mastectomy to improve the aesthetic appearance and function of the axillary region. METHODS: Supplementary silicone implants were inserted for breast reconstruction following mastectomy in 6 female patients, aged 34 to 75 years. The volume of the implants ranged from 20 mL to 120 mL. The width, length, and depth of the axillary region were measured to define the volume and dimensions, as well as the number of implants to be used. The implants were inserted through the scar from the prior breast reconstruction. RESULTS: The follow-up period ranged from 6 months to 8 years, and no capsular contracture was observed. All patients reported functional improvement in arm movement, as well as satisfaction with the aesthetic result, which allowed them to wear more revealing clothing. CONCLUSIONS: The inclusion of semilunar silicone implants as a refinement in breast reconstruction is easy to perform, has predictable results, and requires only one surgical procedure. The implants may be replaced, augmented, or removed, as required.

Analysis of the use of fasciocutaneous flaps for immediate vulvar reconstruction.

OBJECTIVE: To analyze the use of immediate reconstruction techniques of the vulva after surgical resection, with fasciocutaneous flaps of the medial and/or posterior thigh. METHODS: We conducted a transversal, retrospective study to analyse the outcome of immediate surgical reconstruction with fasciocutaneous flaps in nine patients who underwent vulvectomy from May 2009 to August 2010. RESULTS: Mean age was 61 years (range 36-82). In 56% of cases, diagnosis was vulvar intraepithelial neoplasia (VIN), usual type. Radical vulvectomy was performed in 45% of patients, simple vulvectomy in 33% and wide resections in 22%. Eleven fasciocutaneous flaps were made, of which 36.3% were flap transpositions from the posterior thigh, 18.2% from the medial thigh, 18.2% were in advancement flaps, 18.2% simple advancement flaps and 9.1% flap rotation from the posterior thigh. There were no major losses of the flaps made. CONCLUSION: Thigh fasciocutaneous flaps are currently the best options for immediate reconstruction after resection of vulvar cancer due to the preservation of sensibility and tissue availability in the donor areas. The association of the Plastic Surgeon with the Gynecologist offers tranquility for patients and provides good postoperative results.

Profile evaluation of patients with cleft lip and palate undergoing surgery at a reference center in rio de janeiro, Brazil.

In Brazil, the classic timeline for operating on cleft lip and palate is three months old for cheiloplasty and is 12 to 18 months old for palatoplasty. As from Brazilian treatment centers are usually located in major cities, patients living in more remote areas are often unable to receive treatment at the ideal ages. Data were analyzed retrospectively on 45 patients with cleft lip and/or palate, consecutively operated at the Reference Center, Rio de Janeiro Federal University, Brazil. Particularly noteworthy among these data are gender, clinical presentation, operations performed, age of surgery, and the distance between their homes and the hospital. The average age of patients undergoing primary cheiloplasty was 9.4 months, with primary palatoplasties performed at an average age of 7.2 years. As 67% of these patients lived in other towns, they encountered difficulties in seeking and continuing specialized care. Despite attempts to decentralize cleft palate care in Brazil, suitable conditions are not yet noted for following the treatment protocols in a full and adequate manner.

Análise do emprego de retalhos fasciocutâneos para reconstrução vulvar imediata / Analysis of the use of fasciocutaneous flaps for immediate vulvar reconstruction

OBJETIVO: Analisar o emprego de técnicas de reconstrução imediata de vulva, pós-ressecção cirúrgica, com retalhos fasciocutâneos das faces medial e/ou posterior da coxa. MÉTODOS: Estudo de coorte transversal, retrospectivo, para análise do resultado da reconstrução cirúrgica imediata, com retalhos fasciocutâneos em nove pacientes submetidas à vulvectomia, no período de maio de 2009 a agosto de 2010. RESULTADOS: A média de idade foi 61 anos (variação 36 a 82 anos). Em 56% dos casos, o diagnóstico foi neoplasia intraepitelial vulvar (NIV) tipo usual. A vulvectomia radical foi realizada em 45% das pacientes, a vulvectomia simples em 33% e as ressecções amplas, em 22%. Foram confeccionados 11 retalhos fasciocutâneos, sendo 36,3% de transposições de retalho posterior de coxa, 18,2% de retalhos mediais de coxa, 18,2% de retalhos em avanço em V-Y, 18,2% de retalhos em avanço simples e 9,1% de rotação de retalho de região posterior de coxa. Não houve casos de perdas importantes dos retalhos confeccionados. CONCLUSÃO: Os retalhos fasciocutâneos de coxa são, atualmente, boas opções para a reconstrução imediata da vulva pós-ressecção oncológica devido à preservação da sensibilidade e da disponibilidade tecidual nas áreas doadoras. A associação do Cirurgião Plástico com o Ginecologista oferece tranquilidade às pacientes e determina bons resultados pós-operatórios.

Use en autologous plasma in abdominoplasty: previous note.

Autologous plasma began to be studied in the 90's, mainly because its adhesive and angiogenic properties and the presence of growth factors of platelet origin. In fact, plasma can be isolated from autologous manner, from the patient's own blood and obtained in its two parts: a high concentration of platelets (platelet-rich plasma - PRP) and one with low concentration of platelets (platelet-poor plasma - PPP). The present study is in development at the Clementino Fraga Filho University Hospital, Federal University of Rio de Janeiro (UFRJ-HUCFF) and Marcilio Dias Naval Hospital (HNMD), both in Rio de Janeiro. The objective is to evaluate the properties of platelet-poor plasma, particularly its adhesive action, in patients referred for restorative abdominal dermolipectomy, to reduce postoperative collections, such as hematoma and seroma, two major complications in this type of surgery.

Postbariatric buttock contouring with dermolipectomy and gluteal implants.

The authors present their experience with the use of silicone implants in the buttocks after massive weight loss. The procedure is used in combination with gluteal dermolipectomy with or without dermal fat flaps. This report highlights the simplified method of identifying the gluteal muscles, recommends using the superior margin of the gluteus maximus muscle to access the space for implant placement, and prescribes placement of the implants in either the submuscular or the intramuscular space. The described procedure has been performed for two patients to date, with encouraging and long-lasting results.
